A scientist cites fossil evidence to argue that modern whales evolved from relatively small, land-dwelling mammals. The scientist claims that a variety of fossil findings can be ordered in a sequence that demonstrates the evolutionary lineage.

Which analysis of the fossils would be most useful to support the scientist's claim?

A. width and length measurements, which should be the same for homologous bones
B. mineralization analysis, which would identify the specific minerals in each fossils
C. radiometric dating, which would show the absolute age of each fossil
D. biogeography, which should show that all the species lived in the same region.

Scientists who study evolution may want to know whether two present-day species are closely related. Evidence for evolution can be structural, genetic, or bio geographical.  Fossil skeletons of horse relatives dating from various time periods. ... of fossils and living species may tell us how modern organisms evolved. so D

Explanation:

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
